The notation C(n, r) represents the combination function, which calculates the number of ways to choose r items from a set of n items without regard to their order.

The formula for combinations is:

C(n, r) = n! / (r! * (n - r)!)

Now, let's calculate the values of the quantities:

a) C(9, 4):

C(9, 4) = 9! / (4! * (9 - 4)!)

       = 9! / (4! * 5!)

       = (9 * 8 * 7 * 6) / (4 * 3 * 2 * 1)

       = 126

Therefore, C(9, 4) is equal to 126.

b) C(10, 10):

C(10, 10) = 10! / (10! * (10 - 10)!)

         = 10! / (10! * 0!)

         = 1

Therefore, C(10, 10) is equal to 1.

c) C(10, 0):

C(10, 0) = 10! / (0! * (10 - 0)!)

        = 10! / (0! * 10!)

        = 1

Therefore, C(10, 0) is equal to 1.

d) C(10, 1):

C(10, 1) = 10! / (1! * (10 - 1)!)

        = 10! / (1! * 9!)

        = 10

Therefore, C(10, 1) is equal to 10.

e) C(9, 5):

C(9, 5) = 9! / (5! * (9 - 5)!)

       = 9! / (5! * 4!)

       = (9 * 8 * 7 * 6) / (4 * 3 * 2 * 1)

The missing justification in the proof that m<1 = m<3 in Janet's sketch is the Angle Bisector Theorem.

The Angle Bisector Theorem states that if a ray bisects an angle of a triangle, it divides the opposite side into two segments that are proportional to the other two sides of the triangle. In this case, we can assume that m<1 and m<3 are angles of a triangle, and the ray bisects the angle formed by these two angles.

To prove that m<1 = m<3, Janet needs to provide the justification that the ray in her sketch bisects the angle formed by m<1 and m<3.

The probability of having a baby girl using the XSORT method is greater than 0.5. In other words, the method appears to be effective in increasing the likelihood of conceiving a girl.

In a clinical trial conducted by The Genetics and IVF Institute to test the efficacy of the XSORT method designed to increase the probability of conceiving a girl, 325 babies were born to parents using the XSORT method, and 295 of them were girls. This sample data will be used at a 0.01 significance level to determine whether the probability of having a baby girl using this method is greater than 0.5.

The null hypothesis for this test is that the probability of having a baby girl using the XSORT method is less than or equal to 0.5. On the other hand, the alternative hypothesis is that the probability of having a baby girl using the XSORT method is greater than 0.5.The test statistic is the z-score, which can be calculated using the formula:

z = (p - P) / sqrt [P(1 - P) / n],

where p = number of girls born / total number of babies born = 295/325 = 0.908.

P = hypothesized proportion of girls born = 0.5,

n = sample size = 325.

Substituting the values of p, P, and n, we get:

z = (0.908 - 0.5) / sqrt [0.5 x 0.5 / 325] = 12.16

At a 0.01 significance level and with 324 degrees of freedom (n-1), the critical z-value is 2.33 (from a standard normal distribution table). Since our calculated z-value (12.16) is greater than the critical z-value (2.33), we can reject the null hypothesis.

Therefore, we can conclude that the probability of having a baby girl using the XSORT method is greater than 0.5. In other words, the method appears to be effective in increasing the likelihood of conceiving a girl.

Positive value b have an absolute maximum at x= 1-b is a local maximum.

g(x) has a point of inflection on the interval 0 < x < infinity for all values of b in the interval (0,2).

To find the absolute maximum of g(x), we need to find the critical points of g(x) and check their values.

g(x) = [tex]xe^(-x) e^(-b)[/tex]

g'(x) = [tex]e^(-x)(1-x-b)[/tex]

Setting g'(x) = 0, we get:

[tex]e^(-x)(1-x-b)[/tex] = 0

This gives two solutions: x = 1-b and x = infinity (since[tex]e^(-x)[/tex] is never zero).

To determine which of these is a maximum, we need to check the sign of g'(x) on either side of each critical point.

When x < 1-b, g'(x) is negative (since [tex]e^(-x)[/tex]and 1-x-b are both positive), which means that g(x) is decreasing.

When x > 1-b, g'(x) is positive (since[tex]e^(-x)[/tex]is positive and 1-x-b is negative), which means that g(x) is increasing.

Therefore, x = 1-b is a local maximum. To determine whether it is an absolute maximum, we need to compare g(1-b) to g(x) for all x.

g(1-b) =[tex](1-b)e^(-1) e^(-b)[/tex]

g(x) = [tex]xe^(-x) e^(-b)[/tex]

Since [tex]e^(-1)[/tex]is a positive constant, we can ignore it and compare [tex](1-b)e^(-[/tex]b) to [tex]xe^(-x)[/tex] for all x.

It can be shown that xe^(-x) is maximized when x = 1, with a maximum value of 1/e. Therefore, to maximize g(x), we need to choose b such that [tex](1-b)e^(-b) = 1/e.[/tex]

(c) To find the points of inflection of g(x), we need to find the second derivative of g(x) and determine when it changes sign.

g(x) = [tex]xe^(-x) e^(-b)[/tex]

g'(x) =[tex]e^(-x)(1-x-b)[/tex]

g''(x) = [tex]e^(-x)(x+b-2)[/tex]

Setting g''(x) = 0, we get x = 2-b.

When x < 2-b, g''(x) is negative (since [tex]e^(-x)[/tex]is positive and x+b-2 is negative), which means that g(x) is concave down.

When x > 2-b, g''(x) is positive (since [tex]e^(-x)[/tex] is positive and x+b-2 is positive), which means that g(x) is concave up.

Therefore, x = 2-b is a point of inflection.

To find all values of b for which g(x) has a point of inflection on the interval 0 < x < infinity, we need to ensure that 0 < 2-b < infinity. This gives us 0 < b < 2.

Therefore, g(x) has a point of inflection on the interval 0 < x < infinity for all values of b in the interval (0,2).

Newton's law of cooling describes how the temperature of an object changes over time in response to the surrounding temperature. The equation that governs this process is du/dt = -K(u - T), where u is the temperature of the object at any given time, T is the constant ambient temperature, and K is a positive constant.

To find the temperature of the object at any time, we need to solve this differential equation. First, we can separate the variables by dividing both sides by (u-T), which gives us du/(u-T) = -K dt. Integrating both sides, we get ln|u-T| = -Kt + C, where C is a constant of integration. Exponentiating both sides, we get u-T = e^(-Kt+C), or u(t) = T + Ce^(-Kt).

To find the value of the constant C, we use the initial condition u(0) = u_0. Plugging in t=0 and u(0) = u_0 into the equation above, we get u_0 = T + C. Solving for C, we get C = u_0 - T. Substituting this value of C into the equation for u(t), we get u(t) = T + (u_0 - T)e^(-Kt).

Therefore, the temperature of the object at any time t is given by u(t) = T + (u_0 - T)e^(-Kt).
According to Newton's law of cooling, the temperature u(t) of an object can be determined using the differential equation du/dt = -K(u - T), where T is the constant ambient temperature, and K is a positive constant. To find the temperature of the object at any time, given the initial temperature u(0) = u_0, we need to solve this differential equation.

Step 1: Separate the variables by dividing both sides by (u - T) and multiplying both sides by dt:
(1/(u - T)) du = -K dt

Step 2: Integrate both sides with respect to their respective variables:
∫(1/(u - T)) du = ∫-K dt

Step 3: Evaluate the integrals:
ln|u - T| = -Kt + C, where C is the constant of integration.

Step 4: Take the exponent of both sides to eliminate the natural logarithm:
u - T = e^(-Kt + C)

Step 5: Rearrange the equation to isolate u:
u(t) = T + e^(-Kt + C)

Step 6: Use the initial condition u(0) = u_0 to find the constant C:
u_0 = T + e^(C), so e^C = u_0 - T

Step 7: Substitute the value of e^C back into the equation for u(t):
u(t) = T + (u_0 - T)e^(-Kt)

This equation gives the temperature of the object at any time t, taking into account Newton's law of cooling, the ambient temperature T, and the initial temperature u_0.

Thus, the equation that gives the temperature of the object at any time t, considering the initial temperature u_0 and the ambient temperature T is  u(t) = T + (u_0 - T)e^(-Kt).

According to Newton's law of cooling, the temperature u(t) of an object satisfies the differential equation du/dt = -K(u - T), where T is the constant ambient temperature and K is a positive constant.

Given the initial temperature u(0) = u_0, we can solve this differential equation to find the temperature of the object at any time.

To solve the differential equation, we can use separation of variables:
1/(u - T) du = -K dt

Integrate both sides:
∫(1/(u - T)) du = ∫(-K) dt
ln|u - T| = -Kt + C (where C is the integration constant)

Now, we can solve for u(t):
u - T = Ce^(-Kt)

To find the constant C, we use the initial condition u(0) = u_0:
u_0 - T = Ce^(-K*0)
u_0 - T = C

So, our temperature function is:
u(t) = T + (u_0 - T)e^(-Kt)

This equation gives the temperature of the object at any time t, considering the initial temperature u_0 and the ambient temperature T.

The solution to the Cauchy problem is:

u(x,y) = x - y + e^(-(y-1))

To solve the given Cauchy problem, we can use the method of characteristics.

First, we write the system of ordinary differential equations for the characteristic curves:

dy/dt = y+u

du/dt = (x-y)/(y+u)

dx/dt = 1

Next, we need to solve these equations along with the initial condition y(0) = 1, u(0) = 1+x, and x(0) = x0.

Solving the first equation gives us y(t) = Ce^t - u(t), where C is a constant determined by the initial condition y(0) = 1. Substituting this into the second equation and simplifying, we get:

du/dt = (x - Ce^t)/(Ce^t + u)

This is a separable differential equation, which we can solve by separation of variables and integrating:

∫(Ce^t + u)du = ∫(x - Ce^t)dt

Simplifying and integrating gives us:

u(t) = x + Ce^-t - y(t)

Using the initial condition u(0) = 1+x, we find C = y(0) = 1. Substituting this into the equation above gives:

u(t) = x + e^-t - y(t)

Finally, we can solve for x(t) by integrating the third equation:

x(t) = t + x0

Now we have expressions for x, y, and u in terms of t and x0. To find the solution to the original PDE, we need to express u in terms of x and y. Substituting our expressions for x, y, and u into the PDE, we get:

(y + x0 + e^-t - y)(1) + y(Ce^t - x0 - e^-t + y) = (x - y)

Simplifying and canceling terms, we get:

Ce^t = x - x0

Substituting this into our expression for u above, we get:

u(x,y) = x - x0 + e^(-(y-1))

For the first part, we can use a left sum with 4 rectangles to approximate the distance traveled by the vehicle over the first two hours. The velocity function is v(t) = 520t, so the distance traveled is given by the definite integral of v(t) from 0 to 2:

[tex]distance = \int\limits^2_0 \, v(t) dt[/tex]

Using a left sum with 4 rectangles, we have:

distance ≈ [v(0) + v(0.5) + v(1) + v(1.5)]Δt = 0 + 260 + 520 + 780 = 655 miles

Therefore, the distance traveled by the vehicle over the first two hours is approximately 655 miles.

For the second part, we are asked to compute the left and right sums for the area between the function f(x) = 2 - 0.5x² and the x-axis over the interval [-1, 2] using 3 rectangles. We can use the formula for the area of a rectangle to find the area of each rectangle and then add them up to find the total area.

Using 3 rectangles, we have Δx = (2 - (-1))/3 = 1. The left endpoints for the rectangles are -1, 0, and 1, and the right endpoints are 0, 1, and 2. Therefore, the left sum is:

AL = f(-1)Δx + f(0)Δx + f(1)Δx = [2 - 0.5(-1)²]1 + [2 - 0.5(0)²]1 + [2 - 0.5(1)²]1 = 5

The right sum is:

AR = f(0)Δx + f(1)Δx + f(2)Δx = [2 - 0.5(0)²]1 + [2 - 0.5(1)²]1 + [2 - 0.5(2)²]1 = 72

To calculate the deflection at point D using the formula δ=∑NLAE, we need to first segment the rod and then calculate the deflection for each segment.

Segment the rod

Based on the given information, we need to consider segments BD, CD, and AD to calculate the deflection at point D.

Calculate the internal normal force N for each segment

We can calculate the internal normal force N for each segment using the formula N=F1+F2 (for BD), N=F2 (for CD), and N=0 (for AD).

For segment BD

N = F1 + F2 = 140 kN + 55 kN = 195 kN

For segment CD

N = F2 = 55 kN

For segment AD

N = 0

Calculate the cross-sectional area A for each segment

We can calculate the cross-sectional area A for each segment using the formula A=πd²/4.

For segment BD:

A = πd₁²/4 = π(7.6 cm)²/4 = 45.4 cm²

For segment CD

A = πd₂²/4 = π(3 cm)²/4 = 7.1 cm²

For segment AD

A = πd₁²/4 = π(7.6 cm)²/4 = 45.4 cm²

Calculate the length L for each segment

We can calculate the length L for each segment using the given dimensions.

For segment BD:

L = L₁/2 = 6 m/2 = 3 m

For segment CD:

L = L₂ = 5 m

For segment AD:

L = L₁/2 = 6 m/2 = 3 m

Calculate the deflection δ for each segment using the formula δ=NLAE:

For segment BD:

δBD = NLAE = (195 kN)(3 m)/(100 GPa)(45.4 cm²) = 0.0124 m

For segment CD:

δCD = NLAE = (55 kN)(5 m)/(100 GPa)(7.1 cm²) = 0.0392 m

For segment AD

δAD = NLAE = 0

Calculate the total deflection at point D:

The deflection at point D is equal to the sum of the deflections for each segment, i.e., δD = δBD + δCD + δAD = 0.0124 m + 0.0392 m + 0 = 0.0516 m.

In the simpler case of a constant cross section, homogenous material, and constant axial load, the integral can be evaluated to give δ=NLAE. This shows that the deflection is linear with respect to the internal normal force and the length of the bar.

In some situations, the bar can be divided into multiple segments where each one has uniform internal loading and properties. Then the total deflection can be written as a sum of the deflections for each part, δ=∑NLAE.

The circular rod shown has dimensions d1 = 7.6 cm , L1 = 6 m , d2 = 3 cm , and L2 = 5 m with applied loads F1 = 140 kN and F2 = 55 kN . The modulus of elasticity is E = 100 GPa . Use the following steps to find the deflection at point D. Point B is halfway between points A and C.

The absolute difference in the amount of coffee the smaller can hold is then given by |V₁ - V₂| = |178.73 - 157.08| = 21.65 cubic inches.

The formula gives the volume of a cylinder:

V = πr²h, where:π = pi (approximately equal to 3.14), r = radius of the base, h = height of the cylinder

For the larger coffee can,

diameter = 5 inches

=> radius = 2.5 inches

height = 8.5 inches

So,

for the larger coffee can:

V₁ = π(2.5)²(8.5)

V₁ = 178.73 cubic inches

For the smaller coffee can,

diameter = 5 inches

=> radius = 2.5 inches

height = 8 inches.

So, for the smaller coffee can:

V₂ = π(2.5)²(8)V₂

= 157.08 cubic inches

Therefore, the absolute difference in the amount of coffee the smaller can can hold is given by,

= |V₁ - V₂|

= |178.73 - 157.08|

= 21.65 cubic inches.

Thus, the smaller coffee can hold 21.65 cubic inches less than the larger coffee can.

The approximate value of the area enclosed by the curves y = −x⁴/4 + x²/2 + 2 and y = x − 1, for -1.7 ≤ x ≤ 1.7, is 7.12 square units.

First, we need to find the points of intersection between the curves:

y = -x⁴/4 + x²/2 - 2 and y = x - 1

Setting them equal, we get:

Multiplying by -4 to simplify the equation:

x⁴ - 2x² + 4x - 4 = 0

Using a numerical method such as Newton's method, we can find that one of the roots is approximately x = 1.33. The other three roots are complex.

Now, we can set up the integral to find the area between the curves:

A = ∫[tex](-1.7)^{1.33}[/tex] [-x⁴/4 + x²/2 - 2 - (x - 1)] dx + ∫[tex](-1.7)^{1.33}[/tex] [(x - 1) - (-x⁴/4 + x²/2 - 2)] dx

Simplifying the integrals:

A = ∫[tex](-1.7)^{1.33}[/tex] [-x⁴/4 + x²/2 - x - 1] dx + ∫[tex]1.33^{1.7}[/tex] [x⁴/4 - x²/2 + x - 1] dx

Evaluating the integrals:

Therefore, the area between the curves is approximately 7.12 square units.

Given that the water flows through a circular pipe of an internal diameter 3 cm at a speed of 10 cm/s. We are to determine the amount of water that flows from the pipe in one minute and express the answer in litres.

We can begin the solution to this problem by finding the cross-sectional area of the pipe. A = πr²A = π (d/2)²Where d is the diameter of the pipe.

Substituting the value of d = 3 cm into the formula, we obtain A = π (3/2)²= (22/7) (9/4)= 63/4 cm².

Also, the water flows at a speed of 10 cm/s. Hence, the volume of water that flows through the pipe in one second V = A × v where v is the speed of water flowing through the pipe.

Substituting the values of A = 63/4 cm² and v = 10 cm/s into the formula, we obtain V = (63/4) × 10= 630/4= 157.5 cm³. Now, we need to determine the volume of water that flows through the pipe in one minute.

There are 60 seconds in a minute. Hence, the volume of water that flows through the pipe in one minute is given by V = 157.5 × 60= 9450 cm³= 9450/1000= 9.45 litres.

Therefore, the amount of water that flows from the pipe in one minute is 9.45 litres.

Answer: The amount of water that flows from the pipe in one minute is 9.45 litres.

The absolute maximum value of h(x) over the interval [-3,3] is 4.

To find the absolute maximum value, we need to look at the critical points and the endpoints of the interval. Taking the derivative of h(x) and setting it equal to 0, we get 4x-1=0. Solving for x, we get x=1/4.

Plugging this value into h(x), we get h(1/4)=-15/8. However, this is not within the interval [-3,3], so we need to evaluate h(-3), h(3), and h(1/4). We find that h(-3)=10, h(3)=-16, and h(1/4)=-15/8.

Therefore, the absolute maximum value of h(x) over the interval [-3,3] is 4, which occurs at x=-1/2.

The circle with a center at (0, 0) and passing through (0, -3) has an area and circumference that can be calculated. The area can be found using the formula A = πr^2, and the circumference can be found using the formula C = 2πr, where r is the radius of the circle.

Given that the center of the circle is at (0, 0) and it passes through (0, -3), we can determine that the radius of the circle is 3 units. The distance between the center (0, 0) and the point on the circle (0, -3) gives us the radius.

To find the area of the circle, we use the formula A = πr^2. Substituting the radius, we have A = π(3^2) = 9π square units.

To find the circumference of the circle, we use the formula C = 2πr. Substituting the radius, we have C = 2π(3) = 6π units.

Therefore, the area of the circle is 9π square units, and the circumference of the circle is 6π units.

We can use Stokes' theorem to evaluate the line integral of the curl of a vector field F around a closed curve C, by integrating the dot product of the curl of F and the unit normal vector to the surface S that is bounded by the curve C.

Mathematically, this can be written as:

∫∫(curl F) · dS = ∫C F · dr

where dS is the differential surface element of S, and dr is the differential vector element of C.

In this problem, we are given the vector field F = (2y cos z, ex sin z, xey), and we need to evaluate the line integral of the curl of F around the hemisphere x^2 + y^2 + z^2 = 9, z ≥ 0, oriented upward.

First, we need to find the curl of F:

curl F = (∂Q/∂y - ∂P/∂z, ∂R/∂z - ∂Q/∂x, ∂P/∂x - ∂R/∂y)

where P = 2y cos z, Q = ex sin z, and R = xey. Taking partial derivatives with respect to x, y, and z, we get:

∂P/∂x = 0

∂Q/∂x = 0

∂R/∂x = ey

∂P/∂y = 2 cos z

∂Q/∂y = 0

∂R/∂y = x e^y

∂P/∂z = -2y sin z

∂Q/∂z = ex cos z

∂R/∂z = 0

Substituting these partial derivatives into the curl formula, we get:

curl F = (x e^y, 2 cos z, 2y sin z - ex cos z)

Next, we need to find the unit normal vector to the surface S that is bounded by the hemisphere x^2 + y^2 + z^2 = 9, z ≥ 0, oriented upward. Since S is a closed surface, its boundary curve C is the circle x^2 + y^2 = 9, z = 0, oriented counterclockwise when viewed from above. Therefore, the unit normal vector to S is:

n = (0, 0, 1)

Now we can apply Stokes' theorem:

∫∫(curl F) · dS = ∫C F · dr

The left-hand side is the surface integral of the curl of F over S. Since S is the hemisphere x^2 + y^2 + z^2 = 9, z ≥ 0, we can use spherical coordinates to parameterize S as:

x = 3 sin θ cos φ

y = 3 sin θ sin φ

z = 3 cos θ

0 ≤ θ ≤ π/2

0 ≤ φ ≤ 2π

The differential surface element dS is then:

dS = (∂x/∂θ x ∂x/∂φ, ∂y/∂θ x ∂y/∂φ, ∂z/∂θ x ∂z/∂φ) dθ dφ

= (9 sin θ cos φ, 9 sin θ sin φ, 9 cos θ) dθ dφ

Substituting the parameterization and the differential surface element into the surface integral, we get:

∫∫(curl F) · dS = ∫C F ·

(a) The solutions to the equation 2sin(3θ) + 1 = 0 are θ = (π/9) + (2πk/3) or θ = (8π/9) + (2πk/3), where k is any integer.

(b) The solutions in the interval [0, 2π) are θ = π/9, 5π/9.

The given equation is 2sin(3θ) + 1 = 0. To solve for θ, we can start by isolating sin(3θ) by subtracting 1 from both sides and dividing by 2, which gives sin(3θ) = -1/2.

Using the unit circle or a trigonometric table, we can find the solutions of sin(3θ) = -1/2 in the interval [0, 2π) to be θ = π/9 + (2π/3)k or θ = 5π/9 + (2π/3)k, where k is any integer. These are the solutions for part (a).

For part (b), we are asked to find the solutions in the interval [0, 2π). To do this, we simply plug in k = 0, 1, and 2 to the solutions we found in part (a), and discard any values outside the interval [0, 2π).

Thus, the solutions in the interval [0, 2π) are θ = π/9 and θ = 5π/9.
